To all whom it may concern:

{Be it known that 1, DAVID MACLEAN, residingv at Calexi'co, in the county of Imperial and State of California, have invented a new and useful Compound Hydro-Steam tEngine, of which the following is a specificaion.

in a compound hydro-steam engine, in which a plurality of injectors are arranged in combination-with a plurality of series of buckets mountedupon the periphery of a drum in several planes perpendicular to the axle, and

. a plurality of series of deflectors mounted within a case between the series of buckets, to produce power at a convenient speed.

The object of my improvements are: 1. To provide a rotating drum, wheels or disks, mounted upon an axle, with a plurality of series of buckets aflixed tothe periphery thereof. 2. A case to contain the drum and support the bearings for the j ournals of an axle, upon which the drum is mounted. 3. To provide a plurality (two or more) of injectors. 4. To provide manifolds and connections to convey steam and Water to the injectors. 5. A trap in the main steam line to separate air and impurities from the steam.

Figure 1 is anelevation View of the entire engine, with part of the case cut away, showing the end of the drum, with attached buckets around the periphery; also showing the position of the injectors, manifolds, steam trap and connections. Fig. 2 isa cross sectional View along the line and parallel with the center line of the shaft, showing the drum and positions of attached buckets; and

the case, showing the positions of the attached deflectors, and the bearings and axle. The dotted lines indicate disks or arms that may be used-to supporter segmental drum upon which. the buckets are mounted. ,Fig. 3 is a View of an injector,'buckets and deflectors, showing their relative positions, and

the action of the jet of water upon the buckets and deflectors. Fig. 4 is a cross sectional view of an injector, and other allied instruments. Fig. 5 is a detailed view of the buckets, and the deflectorswhich are of similar design. Fig. 6 is. a cross sectional view of a segmental drum. j

Similar letters refer to. similar parts throughout the several views. The bearing 0 Fig. S-supported by the Specification of Letters Patent.

Patented enveloping case A, and with the lugs F forms the framework of theen inc. G' G G are a plurality of injectors attached to the case A by brackets m. These are arranged to discharge the jets in the same relativedirection, and are connected by pipes. 'v'to the manifold D. The main pipe to convey water from a source of supply is connected May 2, 19M.

at the flange W. The pipes i z 2' connect the injectors to the manifold E, which in turn is connected to-a steam boiler at the flange S. The trap H in the main steam line separates air and impurities from the steam, and discharges them at the pet cock '2.

J is a waste pipe to convey the spent water from the engine.

The drum B, Figs. 1 and 2, is mounted upon the axle G, and carries several continuous series of buckets 1, upon the periphery. Wheels or disks, as indicated by the dotted lines M, mounted upon the axle C, may be used to support the buckets.

I and L indicate alternate series of buckets and deflectors. The several series of deflectors are aflixed within the case or upon concentric rings (not shown) secured within the case, and in a reverse position in relation to the buckets. 1

A view through the center line of the jet and parallel with the axle, and through the buckets I I I and deflectors L L, with an i injector G, is shown in Fig. 3. The injector is placedat about the angle to project the jet of water upon the first series of buckets in the direction of the arrow. The direction of the jet of water at this point is partially reversed by impinging upon the first series of buckets. The next first series of deflectors changes the" direction of the jet to about the same angle as the original jet, or in the same direction as the drum rotates. The stream here""impinges, upon the second series of buckets, and deliversitothem a further impulse derived from the momentum of the Water, and so continued throughout theseveral series of buckets and deflectors, until the original velocity of the jet, generated within the injector, is spent.

A cross sectional view of an injector is veyed through the pipe 8. The steam-is- Fig.6 1s. a cross sectional view. Each sec tion, or web of the'drum B, upon which'-- ancing. Each section consisting of a series forced through the nozzle of the pipe 8 causing a partial vacuum in the chamber 0, which supplies the water. In the combining tube 1) the steam and water combine and force the resulting jet through the nozzle a at high velocity.

An enlarged view of the bucket is shown in Fig. 5. e is'a top view, f the side view, and g the end view. This view also shows the deflectors L which are of asimilar pattern. The bucket is curved laterally and.

until out of range of the jet. The transverse curve isas shown. These buckets and deflectors are attached to the drum and case with bolts or screws. A segmental drum is preferred, of which the buckets I are mounted, issupported upon the axle O by arms, or disks, M. This -arrangement facilitates statical or running balof buckets, with webs and disks, are balanced separately, as secured to the axle.

I am aware that steam and water turbines arein use, and disclaim the use of fluids or vapors other than combined steam and water, and using a plurality of jets of water.

I claim:

1. In a compound hydro-steam engine the combination of several injectors, connected to a steam-1ine,; with a plurality of seriesof curved buckets and deflectors as set forth.

2. In a compound hydro-steam engine, having several injectors connected to a steam line, with buckets and deflectors, in combination with a segmental drum, as set forthr 3. In a compound hydro-steam engine having several injectors connected to a steam line, which project their several jets of water directly upon the firstseries, of a plurality of series of buckets combined with a segrment-al drum and a frame within which the several series ofdeflectors are attached.

DAVID MACLEAN.
